Defraggler was written in the same compact architecture as other Piriform products (CCleaner and Recuva). Defraggler is a file defragmentation tool. It differs from other defrag tools on the market, and enables users to quickly and simply defrag the files you want to, without having to process the whole drive. Simply run it, select the file and defragment in seconds.
